Abstract

PURPOSE:To make a floating characteristic stable by using a material having a stiffness smaller than that of the slider material as the core auxiliary material and by polishing this material to concave the core auxiliary part more than the floating face due to difference in stiffness. CONSTITUTION:Ceramic is used as slider materials 4 and 4', and a material of a stiffness smaller than that of slider materials, for example, glass is used as core auxiliary material 5, and this material is joined under a block state by the glass junction method, etc. Next, floating face groove parts 7 and 7' are formed after joining thin film head core part 3. At this time, it is desirable that core auxiliary material 5 and the thin film head core forming base material consist of the same material. Next, all the surface is polished to obtain floating faces 1 and 1' and core auxiliary part 6. At this time, core auxiliary part 6 of a small stiffness is concaved by dimensions d due to difference in material of the surface.
